Re: Nnmi Postgres Database size

Abhishek,

 

  You can use various psql commands to determine the size of the DB and the tables.  The internet has a lot of good information on Postgres.   However for your question you have

 

For the size on disk ( apart from using OS commands ):

 

psql -U postgres
postgres=#select pg_size_pretty(pg_database_size('nnm')) ;

 

Or the internal size of data within the DB

 

psql -d nnm -U postgres postgres=#select SUM(relpages * 8192) AS size_in_bytes FROM pg_class WHERE relnamespace = (SELECT oid FROM pg_namespace WHERE nspname='public') ;

 

  if you need to know how to access the DB then please refer to the KCS document:

  All the best
